This book helps you plan and integrate data relevant to your entire organization. But, when you have shifts in demand, you have to: 1) Realign and cancel hundreds of open manufacturing and purchase orders, and then 2) issue new orders. Another system, kanban, is designed specifically to replenish inventory in just-in-time manufacturing. As consumption occurs, the kanban manual system triggers replenishment signals to the source of supply, so that both production and the supplier are constantly reacting to actual consumption. Compared to MRPII, kanban lowers inventory and minimizes shortages. But the manual process of recalculating every part number by hand, and triggering replenishment by faxing or calling suppliers, is time consuming and non-value-adding. Automating kanban by blending the planning strength of MRPII with manual kanban pull methods enhances your flexibility and competitive position.
